Angle Relationships

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

What is the equation to find the missing angle if two angles are supplementary?

Front

What are Adjacent Angles?

Back

Adjacent angles are two angles that share a common vertex and a common side but do not overlap.

Front

What is the relationship between Corresponding Angles?

Back

Corresponding angles are formed when a transversal crosses two parallel lines. They are equal in measure.

Front

What is the equation to find the missing angle if two angles are complementary?

Back

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie on opposite sides of the transversal and inside the two lines. They are equal when the lines are parallel.

What are Supplementary Angles?

Back

Supplementary angles are two angles whose measures add up to 180°.

Front

What are Complementary Angles?

Back

Complementary angles are two angles whose measures add up to 90°.
